I've some closely related questions about the emergency locator transmitter, ELT, the "distress beacon", on the Airbus A320. From this question about antennas on the A320:
The ELT antenna seems to be located aft of the cabin.
However the ELT might need to be activated manually in case the acceleration sensor doesn't work. More importantly the ELT must be taken away if the crew/passengers decide to move away from the aircraft wreckage, e.g. after a ditching.
It could be interesting to know some details before being the only survivor of a A320 crash in the middle of the Amazon rainforest:
Were is the ELT located and how is it fixed?
How is it manually powered?
How is it connected to the fuselage antenna and to the overhead panel?
Is it possible to remove it from the aircraft and take it away?
